Secondary Development of Computer-aided Design Program Base on VLisp for Railway Station Signal Computer-based Interlocking

In view of the difficulty in preparing the drawings of railway station signal computer-based interlocking at present,a computer-aided design program base on VLisp was developed in this paper. This paper analyzed the system architecture of this program,and also analyzed the keystones of this program,such as how to satisfy the need of supporting a variety of interlocking systems,and how to combine with the coding softwares. Finally,this paper put forward an effective solution,and suggested the improvement direction of this program. It can be seen that the application of this program has greatly facilitated the users and improved the production efficiency.
